COLLAR.

Specification of Letters Patent.

Patented Jan. 18, 19110.

Application filed November 16, 1908. Serial No. 343,719.

To all whom it ma/y concern Be it known that I, MICHAEL L. MCGUIRE,

' of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Collar, of which the following is a specification.

My invention relates to a collar of the classforming the subject-matter of my prior patent No. 686,323, and has for its object the production of means, which augments the strength and durability of the upper end of the collar, and facilitates the making of a tight joint around the pipe passing therethrough, and to this end the invention consists in the combinations and structures hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing,-in which like characters designate corresponding parts in all the views. 1

Figures 1 and 2 are, respectively, plan and elevation of my collar, shown as encircling a piece of pipe Fig. 3 is an enlarged view of parts seen 1n the preceding figures, the illus trated portion of the collar'beingin section. Fig. 4 1s a view similar to Fig. 3, .the upper part of the calking -rin being bent inwardly into contact with t e pipe.

This collar consists of a main shell, a sleeve 1, and a calking ring 2. Said main shell of the collar comprises a base 3 having an upturned tubular part 4, and anipple 5 havin its lower end adjustably mounted on the tu ular part 4, and its upper end provided with a peripheral shoulder 6 spaced apart from the top edge of said nipple, such top edge being deflected outwardly forming a second peripheral shoulder 7 and also a groove 8 in the internal face of the nipple. The base 3 and nipple 5 are connected together by a joint 9 arranged at an angle thereto, and constructed and operating in the same manner as the similar joint set forth in my aforesaid patent, and either the base, or the nipple, may be revoluble about the axis .of such joint for adjusting the collar relatively to the pitch of the roof to be provided therewith.

. The sleeve 1 encircles and reinforces the upper end of the nipple 5 below the upper edge thereof and is prevented from movement endwise thereon in reverse directions by the shoulders 6 and 7, the lower edge of the sleeve being engaged with the shoulder 6, and the upper part of such sleeve having a groove 10 formed therein which recelves 1 inwardly the outwardly-deflected top edge of the nipple 5. Said sleeve 1 is provided with a peripheral shoulder 11 which decreases upwardly in diameter, and is formed with a roove 12 in its lower surface. bling the ni sleeve is pre erably placed upon the nip 16 before the top edge of said nipple is deflected outwardly, and when thesleeve is in position on the nipple with its lower edge in engagement with the shoulder 6, the top In assemple 5 and the sleeve 1', said edge of the nipple is rolled outwardly into the groove 10, thus tightly binding the nipple and the sleeve together, so that neither is capable of movement in any direction relatively to the other. Preferably, the calking ring 2 closely fits, and is fixed to, lower surfaces of the shoulder 11 andjects beyond the top edge of the ni The lower part of the calking rin vided with a shoulder 13 arranged the shoulder 11, and fixed to the lower surface of the shoulder 11, and to a portion of the periphery of the sleeve beneath said shoulder 11, and is formed with a rib 14. which enters the groove 12; and the upper part of such calking ring projects above the main shell of the collar and the sleeve 1, and

ropp e 5. is prodecreases in diameter toward its top for fa- 'eihtating inward bending thereof around the pipe 15 passed through the collar. I

the periphery and upper and beneath v preferably form the calking ring of suitable material, as lead, and cast the same upon the sleeve 1.

In the use of my collar, the upper part of the calking ring is bent downwardly and against the pipe 15, and forms a tight joint between the collar and the pipe.

To those skilled in the art, derstood that the sleeve 1 adds greatly to the rigidity and durability of the upper end of my collar, and also facilitates the practical securement of the calking ring to such collar, and that the described construction of the upper end of the nipple and the sleeve permits of the securement of the sleeve to the nipple at minimum expense and in a substantial manner, which also affords means, as the groove 8, for receiving the bent over upper part of the calking ring.

What I claim is 1. In a collar, the combination with a main shell provided with peripheral shoulders spaced apart, of a sleeve encirclin the main shell between the shoulders, the s eeve it will be unbeing secured to the main shell b said shou ers, and a calking rin carried y the sleeve, the calking ring an sleeve having interlocking parts -substantially as and for the purpose sfieci ed.

2. In a co ar, the combination with a main shell; of a sleeve encircling a ortion of the main shell and provided wit a peripheral shoulder formed with a roove in itslower surface, and a calking ring fixed to the eriphery of said shoulder, and having its lower part providedwith a shoulder fixed to the first-mentioned shoulder and formed with a rib arran ed in said groove, the u per part of the ca king rin projecting a vs the main shell and the s eeve, substantially as and for the pur ose set forth. In testimonywhereof, I ave hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 9th day of November, 1906.
